...look better seconds after application. How? They use optical elements that reflect light (Definity by Olay), pink pigments that enhance skin tone (Clarins' Night Wear) and micro-size sponge-like pearls that fill in pores (Instant Smooth by Clarins). Boutique product Freeze 24/7's claim to fame: gamma amino butyric acid, a natural muscle relaxant that temporarily eases the appearance of fine lines...
Unsure of the structure of a favorite amino acid? No more sifting through pages of results or toggling back and forth among 10 different windows. Harvard affiliates can now access information on more than 20 million chemical compounds, 11 million reactions, and 500 million chemical facts with the click of a mouse, thanks to a search platform the University recently purchased from Elsevier MDL, a leading publisher of scientific information. The software, DiscoveryGate, also allows users to categorize their results and link them to primary sources. Users can look up structures of various compounds, toxicity, metabolic pathways, and suppliers...
...DNA——a conversion that leads to the construction of proteins necessary for life. Kornberg’s discovery, published in the journal Science in 2001, showed in atomic detail the chemical construction of RNA polymerase, a protein complex made of 12 long chains of amino acids with a mass about 10 times that of average protein. To find the structure of large proteins such as RNA polymerase, scientists have to purify them, crystallize them, and then use x-ray crystallography to visualize the structure, according to Jianhua Fu, an assistant professor of biochemistry and molecular...
...plays a role in our ability to develop speech and language, evolved within the past 200,000 years--after anatomically modern humans first appeared. By comparing the protein coded by the human FOXP2 gene with the same protein in various great apes and in mice, they discovered that the amino-acid sequence that makes up the human variant differs from that of the chimp in just two locations out of a total of 715--an extraordinarily small change that may nevertheless explain the emergence of all aspects of human speech, from a baby's first words to a Robin Williams...
...present only in males. And when they compared the two species' proteins--the large molecules that cells construct according to blueprints embedded in the genes--they found that 29% of the proteins were identical (most of the proteins that aren't the same differ, on average, by only two amino-acid substitutions...
